    Abstract: A pixel driving circuit includes a light-emitting control sub-circuit and a plurality of display control sub-circuits. The light-emitting control sub-circuit is connected to a light-emitting control signal terminal, a power supply signal terminal and a light-emitting control node, and is configured to transmit a power supply signal from the power supply signal terminal to the light-emitting control node in response to a light-emitting control signal received from the light-emitting control signal terminal. Each display control sub-circuit is connected to the light-emitting control node, a scan signal terminal, a data signal terminal, and a light-emitting element. Each display control sub-circuit is configured to, in response to a scan signal received from the scan signal terminal, output a driving signal according to the power supply signal and a data signal from the data signal terminal, so as to drive the light-emitting element to emit light.
